Train collision[edit]
On 15 November 2017 at 8.18am, 2 C151A trains collided at this station. A train fault caused the first train heading in the direction of Tuas Link to stall at the station. A minute later, a second train stopped behind the first and then "moved forward unexpectedly", resulting in the collision. 36 passengers and 2 SMRT staff sustained light to moderate injuries, and have been conveyed to nearby hospitals.[3][4][5]
Investigation found that the first train had a safety protection feature removed when it went over a faulty signalling circuit.[6] That safety protection feature was designed to fix a known bug which wrongly designated the six-car train as a three-car train under certain circumstances.[6] While the first train was being detrained and the automatic platform doors were opened, a separate protection module was activated to block off the entire length of the westbound platform. The module notified the second train's signalling computer that the westbound platform was occupied and to stay clear of the platform.[6] The second train stopped at the correct distance behind the first train while the automatic platform doors were open. However, once the doors were closed, the platform length protection module was removed. When the signalling on the second train detected the first train as only three cars instead of six, it started moving to close the perceived gap between both trains for the distance of three cars, thus allowing the acceleration of the second train and the rear-end collision with the first train.[6]
